SPECIFICATION forming part of Letters Patent No. 579,956, dated April 6,1897.

Application filed March 2 9, 18 9 5.

To all whom it may concern:

Be it known that I, CHARLES M. CHAPMAN, a citizen of the United States,residing at Fort Edward, inthe county of \Vashington and State ofNewYork, have invented certain new and useful Improvements in Strainers;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon.

This invention relates to certain improvements in strainers.

The object of the invention is to provide a strainer exceedingly cheapand simple in construction and composed of a minimum number of parts andso arranged that the several parts composing the same can be easilydetached for purposes of cleaning, the.

The invention consists in certain novel features of construction and incombinations and arrangements of parts more fully and particularlypointed out hereinafter.

Referring to the accompanying drawings, Figure 1 is a vertical section.Fig. 2 is a perspective view of the clamping-ring for holding thestrainer-disk in position.

A represents the funnel-shaped body, constructed of sheet metal andprovided at its lower end with an inwardly-projecting supporting-flangea, formed with the neck Z). Over the neck Z) fits the rim 0 upon theupper end of a flaring support B, which has perforations d to allow theescape of the strained liquid when said support is in use. Upon thesupporting-flange a rests the strainer-disk C, which may be ofperforated sheet metal or wire-gauze, as found best adapted to the kindof liquid to be strained. In connection with this metal strainer-disk Cmay be used a strain-cloth D of any desirable fineness, which may beheld in place between the neck I) and rim 0, as shown,'or upon theinside of the neck and the metal strainer-disk placed thereon, as founddesirable.

By the employment of the cloth in addition to the metal strainer-disk amore perfect straining of the liquid is obtained, as the impurities orforeign bodies passing through the perforations or meshes of the metaldisk are Serial No. 543,682. (No model.)

taken up by the cloth and prevented from passing through the strainer.

A very simple and effective device is provided for holding the metalstrainer-disk in .place,which device consists of a spring clamp- 5 5ing-ring E, constructed of suit-able wire. The ends of the wire formingthe ring are bent to present vertically-projecting arms F, and theextremities of these arms have curved ends to form bearings orthumb-pieces e to be used in pressing the two arms together when thering is to be contracted. After the strainer disk and cloth are in placethe ring E is contracted by pressing together the arms F and the ringinserted within the strainer immediately over the disk 0, and byremoving the pressure from the arms the ring will expand to its originalsize or sufficiently to be held in place by frictional contact with theinterior of the neck Z).

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

The herein-described strainer composed of an approximately funnel-shapedbody having the wide-flaring top opening and the neck I), the lowerportion of said body terminating in the inwardly-projecting flange a,formed on the lower edge of the neck of said funnelshaped body, thecircular-shaped removable 8o strainer 0, consisting of a disk resting onsaid inwardly-projecting flange a, the spring-wire clamping-ring Elocated within said opening as described, the two arms F extendingupwardly therefrom having their upper ends curved or bent over to formtwo separate thumb-pieces e, the rim 0, the straining-cloth D betweenthe neck I) and the said rim 0, and the flaring support B adapted tosupport the body A, the funnel body being provided with 0 perforations din the lower part thereof for the escape of liquid as and for thepurpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence 5 of two witnesses.

CHARLES M. CHAPMAN.
